The book by Rytek Kutas is universally considered the bible for curing meats. Good stuff in there.
Mario Batali's father runs a salumeria in Washington state, where he makes and cures his own proscuitto, salami, salume, sopresatta, etc... The name escapes me at the moment. But there are other artisnal curers out there, who I'm sure would be willing to give you a few hints.
I'll check some old cooking magazines to see what I can round up for you.
